Solar plans in Egypt
Solar PV - clean energy, wobbly finance
Mixed news on solar generation of electricity On the one hand, buyers of homes are steering clear of homes with leased solar PV panels on the roof, because of uncertainty and complications surrounding the owners of the panels - a private company, and the guarantors of the tariffs - government. It's hardly news that a week is a long time in politics, so a twenty five year guarantee of feed in

Solar energy to produce hydrocarbons from climate change pollutants
Recent breakthroughs in semiconductor physics have produced the possibility of using solar energy (photovoltaic generation) to capture CO2 (carbon dioxide) from the atmosphere, but, most importantly, to do so where it is being produced by industrial use of carbon based fuels which currently contribute to climate change pollution. Using DC electricity to electrolyse water into Hydrogen and

energy policy for a sane species
Imagine that the human race was capable of consideration for others, rationality and honesty. What would the world's energy supply look like? The most recent estimate of global energy consumption is for 2013 - 5.67 10^20 joules A kilowatt hour is 1000 x 60 x 60 joules = 3,600,000 joules = 3.6 10^6 joules. So energy consumption is approximately 2.10^14 kilowatt hours per year. For those

Comfrey organic compost experiment
I'm a fan of Comfrey as a mineral mine (especially potassium) for organic growers, but the standard advice to delay your potato planting until the first cut of Comfrey is ready (typically about 5% of the annual crop) makes little sense. So I experimented: Last years' compost bin had 1 bale of wetted straw, a year's growth of Comfrey from 10 plants (about 200 lb), and approximately 200 lb of

climate change threatens healthy diet
Environment degradation due to climate change has serious implications for the wellbeing of the world due to poorer  diet and food shortages over the next 35 years: Climate change could kill more than 500,000 people a year globally by 2050 by making their diets less healthy, according to new research published in the Lancet. The research is the first to assess how the impacts of global

Arizona climate prospects
Four recent studies from the climate research center at the University of Arizona have detailed a variety of impacts on the environment in Arizona: A steady rise in global temperatures since the 1970s has already shifted the high-altitude jet stream to the north by more than 1,000 miles. That shift has dragged the winter and spring storm track with it. The change will result in fewer big

1.2 gigawatt offshore wind farm
Currently the world's largest offshore wind farm has been given the go ahead in the North Sea, 75 miles east of Hull, England. The 1.2 gigawatt (1,200,000 kilowatts) is expected to generate enough power for one million homes. Wind power is crucial for the UK, as we experience more wind in the winter when solar power is minimal. The Danish firm Dong Energy is investing in the project, and

Solar power inverters - efficiency and self-reliance
Tata, the car manufacturer (and more) and one of the first to make a budget electric car, now has an offshoot called Tata Power Solar. It is releasing a solar PV unit that stores electricity from PhotoVoltaic panels in batteries to power an inverter (to mains AC) to replace the domestic mains when there is a power cut. This is designed for helping customers in remote and poor areas where

new solar thermal material

tree frog squats in bird box
A tree frog moved into my wren house. He's enjoying the view from the front porch.  The Wren house is a hollow plastic ball that I drilled a 1 1/4 inch entry hole and drainage holes. I've tried wood Wren houses but Sparrows always peck at the entry hole until it's big enough for them to fit in....the Wrens are chased away. The plastic ball has worked. A Wren couple moved in last Spring.

Solar PV progress
The Journal of Renewable and Sustainable Energy has published a report on the problems of merging large scale PV (photovoltaic) solar energy generation with existing AC (alternating current) distribution systems (like to your home and businesses).

Renewable energy storage
A 5 megawatt Li-Ion battery storage facility has been opened in Oregon, U.S.A. It is only a demonstration project, as the cost of storing excess energy from renewable sources such as solar and wind generation is still not a practical solution. This demonstration is part of a micro-grid - a local grid that stores energy for the local community, and it can even provide power when the national grid

Electric car charging in Manchester

coral reef destruction, sand lizard revival
Climate change and coral reef destruction Current climate targets are not enough to save the world's coral reefs - and policymakers urgently need to consider the economic benefits they bring. Those are two of the conclusions from a UN-backed project aiming to quantify the financial costs of damaging nature. “ There's evidence that current levels of CO2 are already causing damage to reefs

Solar farms in Egypt
Annual Solar Energy input to Earth With an average level of solar radiation between 2,000 to 3,200 kWh per square metre a year, Egypt has significant potential for solar energy. To date, however, uptake of solar projects has been slow because of high capital costs, but the country has recently moved to expand its solar capacity. 3,000 kWh over 365 days would power a well-designed, energy

Return of the Ravens
Not a gothic band or dubious bankers - THE BIRDS! On the news yesterday was a report that Ravens, which had spread from the West Country, Wales, the Lake District and Scotland into the more heavily populated areas to the South and East, had finally set up base in Kent, near the white cliffs of Dover. A pair of Ravens succesfully nested last year and have two bambinos! :) Well done the Ravens.
